Evaluation of the combination of the dual m-TORC1/2 inhibitor vistusertib (AZD2014) and paclitaxel in ovarian cancer models.
(IMPACT JOURNALS LLC, 2017-12-26)Activation of the PI3K/mTOR pathway has been shown to be correlated with resistance to chemotherapy in ovarian cancer. We aimed to investigate the effects of combining inhibition of mTORC1 and 2 using the mTOR kinase ... -
Evaluation of the Response of Intracranial Xenografts to VEGF Signaling Inhibition Using Multiparametric MRI.
(ELSEVIER SCIENCE INC, 2017-09-01)Vascular endothelial growth factor A (VEGF-A) is considered one of the most important factors in tumor angiogenesis, and consequently, a number of therapeutics have been developed to inhibit VEGF signaling. Therapeutic ... -
Evaluation of therapeutic radiographer contouring for magnetic resonance image guided online adaptive prostate radiotherapy.
(ELSEVIER IRELAND LTD, 2023-03-01)BACKGROUND AND PURPOSE: The implementation of MRI-guided online adaptive radiotherapy has facilitated the extension of therapeutic radiographers' roles to include contouring, thus releasing the clinician from attending ... -
Evaluation of three presets for four-dimensional cone beam CT in lung radiotherapy verification by visual grading analysis.
(BRITISH INST RADIOLOGY, 2016-07-01)OBJECTIVE: To evaluate three image acquisition presets for four-dimensional cone beam CT (CBCT) to identify an optimal preset for lung tumour image quality while minimizing dose and acquisition time. METHODS: Nine patients ... -
Exercise reduces immune suppression and breast cancer progression in a preclinical model.
(Impact Journals, LLC, 2020-01-28)Exercise is associated with favorable changes in circulating immune cells and improved survival in early-stage breast cancer patients, but the mechansims remain to be fully elucidated. Preclinical studies indicate that ... -
An exploration of mechanisms and effects of oncogenic KRAS on the tumour immune microenvironment
(Institute of Cancer Research (University Of London), 2022-07-06)Oncogenic KRAS influences several cancer hallmarks including autonomy from growth promoting signals, enhanced cell survival and altered tumour metabolism. Beyond these, it is now established that oncogenic KRAS can polarise ... -
Exploration of the treatment challenges in men with intellectual difficulties and testicular cancer as seen in Down syndrome: single centre experience.
(BMC, 2015-06-26)Down syndrome is the most common chromosomal disorder in humans as well as the most common cause of inherited intellectual disability. A spectrum of physical and functional disability is associated with the syndrome as ... -
Exploring the roles of urinary HAI-1, EpCAM & EGFR in bladder cancer prognosis & risk stratification.
(Impact Journals, LLC, 2018-05-18)OBJECTIVES: To investigate whether elevated urinary HAI-1, EpCAM and EGFR are independent prognostic biomarkers within non-muscle-invasive bladder cancer (NMIBC) patients, and have utility for risk stratification to ... -
Expression of the mono-ADP-ribosyltransferase ART1 by tumor cells mediates immune resistance in non-small cell lung cancer.
(AMER ASSOC ADVANCEMENT SCIENCE, 2022-03-16)Most patients with non-small cell lung cancer (NSCLC) do not achieve durable clinical responses from immune checkpoint inhibitors, suggesting the existence of additional resistance mechanisms. Nicotinamide adenine dinucleotide ... -
Expression profiling of single cells and patient cohorts identifies multiple immunosuppressive pathways and an altered NK cell phenotype in glioblastoma.
(OXFORD UNIV PRESS, 2020-03-11)Glioblastoma (GBM) is an aggressive cancer with a very poor prognosis. Generally viewed as weakly immunogenic, GBM responds poorly to current immunotherapies. To understand this problem more clearly we used a combination ... -
Extended T2-IVIM model for correction of TE dependence of pseudo-diffusion volume fraction in clinical diffusion-weighted magnetic resonance imaging.
(IOP PUBLISHING LTD, 2016-12-21)The bi-exponential intravoxel-incoherent-motion (IVIM) model for diffusion-weighted MRI (DWI) fails to account for differential T 2 s in the model compartments, resulting in overestimation of pseudodiffusion fraction f. ... -
Extracranial Soft-Tissue Tumors: Repeatability of Apparent Diffusion Coefficient Estimates from Diffusion-weighted MR Imaging.
(RADIOLOGICAL SOC NORTH AMERICA, 2017-07-01)Purpose To assess the repeatability of apparent diffusion coefficient (ADC) estimates in extracranial soft-tissue diffusion-weighted magnetic resonance imaging across a wide range of imaging protocols and patient populations. ... -
Extrameningeal solitary fibrous tumors-surgery alone or surgery plus perioperative radiotherapy: A retrospective study from the global solitary fibrous tumor initiative in collaboration with the Sarcoma Patients EuroNet.
(WILEY, 2020-07-01)BACKGROUND: Solitary fibrous tumor (SFT) is a rare mesenchymal malignancy. Although surgery is potentially curative, the local relapse risk is high after marginal resections. Given the lack of prospective clinical trial ... -
